The book of Acts is transitions , not an 'example '. The early Church in the bible is not given as 'example ' in the book of Acts . No verse tells us to do this in the epistles.
No verse says it is a transition either.
1Tim 4:14; Do not neglect the spiritual gift within you, which was bestowed on you through prophetic utterance with the laying on of hands by the presbytery.
2Tim 1:6; For this reason I remind you to kindle afresh the gift of God which is in you through the laying on of my hands.
Heb 6:2; of instruction about washings and laying on of hands, and the resurrection of the dead and eternal judgment.
At the most you could take Acts 2 as a transition, it was the first time the Holy Spirit fell on the church corporately. All of the other instances in Acts, were just a matter of business as usual.
It's interesting to note that most scholars think Luke was likely a Gentile (there isn't really proof of this in the Bible)
Also while Paul wrote more books than Luke, Luke wrote more words. Luke and Acts have more words than all of Paul's books together. Luke actually wrote more of the New Testament than Paul.
It's also interesting to note, that of the 5 "baptism in the Holy Spirit" instances mentioned in Acts, more than half were Gentiles. (3 out of 5)
The Samaritans in chapter 8. Cornelius in chapter 10, and the disciples at Ephesus in chapter 19.
As far as no verse in the Epistles talking about the gifts of the Spirit...
1Cor 12:7; But to each one is given the manifestation of the Spirit for the common good.
1Cor 12:8; For to one is given the word of wisdom through the Spirit, and to another the word of knowledge according to the same Spirit;
1Cor 12:9; to another faith by the same Spirit, and to another gifts of healing by the one Spirit,
1Cor 12:10; and to another the effecting of miracles, and to another prophecy, and to another the distinguishing of spirits, to another various kinds of tongues, and to another the interpretation of tongues.
1Cor 12:11; But one and the same Spirit works all these things, distributing to each one individually just as He wills.
1Cor 14:1; Pursue love, yet desire earnestly spiritual gifts, but especially that you may prophesy.
1Cor 14:2; For one who speaks in a tongue does not speak to men but to God; for no one understands, but in his spirit he speaks mysteries.
1Cor 14:3; But one who prophesies speaks to men for edification and exhortation and consolation.
1Cor 14:4; One who speaks in a tongue edifies himself; but one who prophesies edifies the church.
1Cor 14:5; Now I wish that you all spoke in tongues, but even more that you would prophesy; and greater is one who prophesies than one who speaks in tongues, unless he interprets, so that the church may receive edifying.
1Cor 14:31; For you can all prophesy one by one, so that all may learn and all may be exhorted;
1Cor 14:32; and the spirits of prophets are subject to prophets;
1Cor 14:33; for God is not a God of confusion but of peace, as in all the churches of the saints.
